Overview

EN 1822-1:2019 is the CEN European standard that defines classification, performance testing and marking for high efficiency air filters - EPA, HEPA and ULPA - used in ventilation, air conditioning and technical processes (for example cleanrooms and pharmaceutical production). The standard establishes a particle-counting test procedure (liquid aerosol, alternatively solid for leak checks) to determine filter efficiency at the most penetrating particle size (MPPS) and to assign filters to standardized classes (E10–E12, H13–H14, U15–U17).

Key topics and technical requirements

  • Scope & classification
    • Covers EPA, HEPA and ULPA filter elements and assigns groups/classes by integral and (for H and U) local MPPS efficiency/penetration.
    • Classes: E10–E12, H13–H14, U15–U17.
  • Measurement basis
    • Particle-counting methods using a liquid test aerosol (e.g., DEHS, PAO, PSL). Solid aerosols allowed for some leak tests.
    • Determination of MPPS from sheet-media efficiency vs particle size curves.
  • Three-step test process
    1. Flat sheet filter media test to determine MPPS and baseline efficiency.
    2. Leak test of the filter element (mandatory for Groups H and U; Group E not leak-tested for classification).
    3. Efficiency test of the assembled filter element at the nominal air volume flow rate.
  • Test conditions
    • Typical test air temperature (23 ± 5) °C and relative humidity < 75%, with tighter stability during tests.
    • Clean test air (background particle concentration control - e.g., < 352,000 particles/m³).
  • Performance metrics
    • Integral efficiency/penetration at MPPS and, for H/U groups, local (scan) leakage limits.
    • Special handling for electrostatically charged media - classification based on discharged efficiency (per EN ISO 29463-5).
  • Documentation & marking
    • Test reports, marking and traceability requirements for manufacturers and testing laboratories.

Practical applications

  • Specifying and verifying filters for:
    • Cleanrooms (semiconductor, biotech, medtech)
    • Pharmaceutical manufacturing and aseptic processing
    • Hospital HVAC and isolation rooms
    • Critical industrial processes requiring particle control
  • Used by: filter manufacturers, independent test laboratories, HVAC engineers, cleanroom qualification teams, procurement/specification authors and regulatory bodies.

Who should use this standard

  • Manufacturers for product classification and marking
  • Test laboratories for accredited performance testing
  • Engineers and facility managers for selecting and validating filters in controlled environments

Related standards

  • EN ISO 29463-2 / -3 / -4 / -5 (aerosol production, sheet media testing, scan leak method, filter element testing)
  • EN 14799 (terminology)
  • EN ISO 5167-1, ISO 2859-1 (measurement & sampling references)

EN 1822-1:2019 supersedes EN 1822-1:2009 and emphasizes particle-counting methods (it excludes the aerosol-photometer scan leak test), making it the reference for modern HEPA/ULPA performance classification and testing.
